Hi,
I've had CoordTrans v2.30 for a little while and have found it extremely useful. There are a couple of things I need help with however. The other day
I tried to obtain geographic coordinates for some X-Y locations in Austria which apparently refer to the Austrian M31 coordinate system. However,
CoordTrans consistently plots these locations in West Africa (Cameroon-Gabon border). Here is the first example
X=463780
Y=268630
I've checked all the M31 parameters in Coordtrans and they appear to be correct -can anyone tell me why it's not working? (I'm a GIS newbie as is probably obvious).

The reason I asked was that I have similar coordinates in a separate paper by the same authors so it's likely to be a genetic error. I'll write to the authors and clarify that.
I have maps that I can visually check the coordinates with anyway (see references below).
